Description

Signaling by light on motor vehicles The invention relates on signaling by light on motor vehicles when switched on Vehicle lighting and regardless of which lighting level is switched on a periodic lighting up of the high beam of both headlights is effected.

Signaling by light in motor vehicles during the dark is becoming increasingly popular. Once there is this noiseless type of signaling perceived as pleasant, and on the other hand this way is often more effective than a horn signal. It has already been proposed that only one headlight should be illuminated periodically to indicate an intended change of direction.

In its simplest form, the process of signaling occurs either by pressing the dimmer switch installed in every vehicle several times, or the high beam coils are usually attached to the steering device via a Push button supplied separately with power, as often and as long as this contact is closed will. When the high beam is switched on, the previous switch to low beam is here necessary.

Circuits have already been proposed to automate the process where an automatically operating device during signaling a switchover from one luminaire to one in a periodically recurring sequence others do. Another suggestion takes place periodically Change between the normal brightness of the headlights and complete deactivation instead of. A disadvantage of these circuits is the use of changeover switches with their periodically moving Switch parts and contacts that are subject to heavy wear and are subject to your scorching .. The periodic change between light signal and complete deactivation results in an increased moment of danger, since in the blinking pauses is driven with insufficient lighting. Another disadvantage turns out to be the permanent inclusion of the turn signal switch in the headlight circuit, even if they are operated with permanent light.

The invention avoids these disadvantages by a circuit at when the high beam is switched on, as long as the control switch for flashing the high beam is closed, the normal power supply to the high beam, vendeln the headlight interrupted and instead a permanent power supply to the The dipped filaments of the headlights are closed and, in addition, the high beam filaments periodically activated via a flasher unit located in a separate circuit and be turned off. It is more advantageous to use% veis (@ for the duration of the signaling only a one-time switchover takes place during the periodically recurring power supply of the high beam coils is done by the flasher unit, which is in one of the permanent power supply ge. separates arranged circuit.

The drawing shows a circuit diagram according to the proposal of the invention. The faint lines denote the normal wiring of a motor vehicle with the components ignition switch i, light switch 2, dimming switch 3, headlights 4 and high beam control 5. The headlights contain high beam coils 4a, dipped coils 4b and parking lights 4c. The solid lines indicate the additional wiring according to the invention with the components flashing switch 6, switching relay 7 and signal push button B. The switching relay contains a normally closed contact 7 a and two normally open contacts 7 b and 7 c. The terminal designations that are still used correspond to the numbers generally used in automotive electrical engineering. To increase the visibility, the fuses have been omitted and the cable routing has been shown in a simplified manner. It should also be noted that terminal 58 in light switch 2 is always live when terminal 56 is also live. This corresponds to the currently applicable German regulations and can easily be achieved at a later date for other motor vehicles.

Signals are emitted by pressing the signal button B. The battery current flows through the coil of the switching relay 7, the contact arms are attracted and the normally closed contact 7 a is opened and the normally open contacts 7 b and 7 c are closed. The direct power supply to the high beam filaments 4a, the A of the dip switch 3 of carried, is of the contact 56 through the open-closed contact 7a interrupted and is now the contact 58 of the light switch 2 from above and in the rhythm of the indicator lights 6 and working contacts 7 b instead. So periodic light pulses are sent out with the help of a normal flasher. Whether one lets the working contacts of the relay work directly or with the interposition of a contactor, not shown in the drawing, depends on the load capacity of the relay contacts.

With the switching of the switching relay 7 current is over the working contact c 7 from the terminal 56a to Abblendlichtwendeln 4 b as long as the permanent current supplied ,. how the contact 8 is kept closed. This ensures adequate lighting of the roadway and also of the vehicle during the blinking breaks.

The mode of operation of the subject matter of the invention is as follows: The vehicle has high beam: terminals 58, 56 and 56a are live. When you press the signal button 8 for the flashing of the high beam, the connection between the terminal 56 a of the dimming switch and the high beam coils 4a. the headlight interrupted at contact 7a. To do this, they periodically receive current from contact 58 via the flasher switch 6 and contact 7b . During the signaling, the dimming coils 4b receive continuous current from. 56a over 7c. After the signaling process has ended, the vehicle has high beam again.

Of course, it is also possible to use the signaling when the parking lights or low beam are switched on. The following cases arise here: a) The vehicle only has parking lights: Terminal 58 is live. When the signal button 8 is pressed for the flashing of the high beam, the high beam coils 4a of the headlights are periodically energized via the flasher switch 6 and contact 7b from terminal 58. The parking lights .Ic continue to burn during the pauses in the blinking. After the flashing signal has ended, the vehicle has parking lights again.

b) The vehicle has dipped headlights: terminals 58, 56 and 56b are below Tension. By pressing the signal button 8, the high beam coils 4ca light up periodically on. During the pauses in the blinking and after the signaling process, the dipped headlights continue to burn.
